Abstract

We present the design of an ultra-compact polarization beam splitter where three symmetrical dielectric channel waveguides are hybrid integrated with Au plasmonic waveguide arrays. Ultra-wideband operation over 50 THz with the insertion loss less than 2 dB for both transverse electric and transverse magnetic mode are predicted. The extinction ratio is better than 15 dB for both polarizations and it is realizable on a chip size as small as 0.93 × 4.2 μm2.
